[101] Reference 0-20 mA Par. 3-00 [Min - Max] 0% = 0 mA; 100% = 20 mA
Par. 3-00 [-Max - Max] -100% = 0 mA; 0% = 10 mA; +100% = 20 mA

[103] Motor current 0-20 mA Value is taken from par. 16-37. Inverter max. current (160% current) is equal to 20 mA.
Example: Inverter norm current (11 kW) = 24 A. 160 % = 38.4 A. Motor norm current = 22 A Read-
out 11.46 mA.

[138] Torque 4-20 mA Torque reference related to 160% torque.
[139] Bus ctrl. 0-20 mA An output value set from fieldbus process data. The output will work independently of internal
functions in the frequency converter.
[140] Bus ctrl. 4-20 mA An output value set from fieldbus process data. The output will work independently of internal
functions in the frequency converter.
[141] Bus ctrl. 0-20 mA, timeout Par. 4-54 defines the behaviour of the analog output in case of bus time-out.
[142] Bus ctrl. 4-20 mA, timeout Par. 4-54 defines the behaviour of the analog output in case of bus time-out.

6-71 Terminal X45/1 Output Min Scale
Range: Function:
0.00%* [0.00 - 200.00%] Scale the minimum output of the selected analog signal at terminal X45/1, as a percentage of the
maximum signal value. E.g. if 0 mA (or 0 Hz) is desired at 25% of the maximum output value, then
programme 25%. Scaling values up to 100% can never be higher than the corresponding setting
in par. 6-72.
